'CUTTING MECHANISM.

Specification of Letters Patent.

Patented May 4, 1915.

Application filed. August 1 2, 1913- Serial No. 784,465.

citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented. certain new and useful Improvements in Cutting Mechanism,

of which the following is a specification.

This invention relates to improvements in cutting mechanism, and particularly the cuttingmechanism of machines such as slotting machines for slotting cardboard, etc. In machines of this type as ordinarily constructedit is customary to employ a series of cutters or knives and mount these on a suitable support, such as a cutter-bar, in such a manner that the knives will cut in parallel planes to form parallel slots in the material. Ordinarily these cutters or knives are mounted on knife-holders which are secured to the cutter-bar in such a manner that they may be adjusted to different positions in the length of the cutter-bar and secured in such positions for operation. The knifeholders employed are relatively narrow and it has been' found that in practice they do not support the knives as rigidly crosswise thereof as is desirable, for which reason the knives are almost invariably worn on the 7 side in such a manner as to indicate that in operation the movable knife strikes on the side as it works up and down and is correspondingly worn on the side, owingto the insufficient support afforded by each relatively narrow knife-holder.

The principal object of the present invention is to provide an extended support for each knife and knife-holder which support will be sufficient to prevent the slight tipping or canting of the knife-holder that takes place when this holder is of the usual relatively narrow type just described.

A further object of the invention is to provide such an extended support for each knife and its knife-holder without increasing the width of any knife-holder and without interfering in any way with the adjustment of the same crosswise of the knives or preventing such holders from being brought and in the preferred construction cooperates with the cutter-bar and the knife-holder in such a manner as to assure themaintenance of these parts in a predetermined relation crosswise of the knife-holder, so that no sidewise tipping or canting of the knife and its holder can occur after the holder and the extended support have been properly secured in position on the main support for the knife-holder. In order that each knifeholder and its knife may have a relatively great extended support crosswise of the knife, I employ a series of devices, one for each knife-holder, which devices are disposed in different positions crosswise of the knives and in such a manner that no one of them will interfere with the adjustment or operation of the knife, knife-holder or extended support of any other ,cutting unit, this result being accomplished in any one of various ways.

Other features of the invention not hereinbefore referred to will be hereinafter described and claimed and are illustrated in the accompanying drawings, in which Figure 1 is a sectional end elevation of a cutting mechanism embodying upper and lower cutters, cutter-holders and supports, etc., constituting, in this case, part of a slotting machine andembodying my present invention; Fig. 2; is aplan on a smaller scale of a portion of the same with the upper cutter-bar or supportremoved; Fig. 3 is a view similar to Fig. 1 of a modification of the invention showing another species of the extended support for the upper cutters or knives; Fig. 4 is a plan of the same; Fig. 5 is a view similar to Fig. 3 of the lower portion of the cutting mechanism illustrating a modification embodying an extended support for the lower cutters or knives, and Fig. 6 is a plan of the same.

Similar characters designate like parts in all thefigures of the drawings.

Referring first to Figs. 1 and 2, 2 and 3 designate respectively upper and lower supports for knife-holders and knives, the upper being the usual cutter-bar or cross-head, while the lower is the bed with ways thereon of a slotting machine. On these supports 2 and 3 are mounted upper and lower knifeholders, designated generally by 4: and 5, respectively, the former being preferably adf justable lengthwise of the cutter-bar 2 and the latter being adjustable similarly lengthwise of the bed 3. Each of the main sup ports 2 and 3 has the usual inclined or dovetailed ways, 2 and 3, cooperating with cortening means which secure the knife-holders 4 and 5 to said supports, said fastening means usually being gibs, such as 8 and 9,

suitably bolted in place. v

The .principal knife-holders 4, it will be noticed, (see Fig. 2) are the usual relatively narrow holders capable of adjustment close up to one another to permit the knives 6 to cut parallel slots relatively close together. For each of these knife-holders extended supports are shown for preventing transverse tipping or canting movement of the holders and knives. These devices are such, in these views, as to provide transverse supports for. the knife-holders and knives several times as long as the support afforded by the knife-holder itself. The specific construction shown is one in which'a supporting bar, such as 10, is securely fastened to the knife-holder 4, preferably'in a transverse groove, 11, in the upper edge thereof, and extends beyond each side of said Iknife holder a distance preferably equal to or greater than the entire widthof said knife-holder. This bar constitutes a slidebar intended to move back and forth in a corresponding groove, such as 12, which is cut in the under sideof the cutter-bar 2 and in which said slidebar fits and 'works, the construction being such that when the clamping means is tightened up said slide-bar will also be secured in place in the groove 12, and all of the parts being tightly held together, will give a substantially rigid support transversely for the knife of the full length of said slide-bar.

Referring to Fig. 2, it will be seen that each of the knife-holders 4 has aslot 11in the upper side thereof all of these slots being in alinement with one another. The object of this is-to permit the knife-holders to be brought into contact if desired while still providing for the support of each knife transversely along the surface of the full length of each slide-bar 10. In Fig. 2 it will be seen that one end of said slide-bar'lO extends into the groove llof the next knifeholder. If the knife-holders were in contact with one another this slide-bar would extend into the slot-11 of the third knife-holder.

' In addition to providing an extended support the full length of which is available as a supporting means regardless of the adj ustment of the knife-holders relatively to one another on the cutter-bar, I also provide means for furnishing an extended support for each of a series of knife-holders without I any interference of one knife-holder with the proper adjustment or support of any other. In order to accomplish this result the extended supports are shown as disposed in different positions crosswise of the knives, they being illustrated in the construction shown in Fig. 2 as parallel with one another. Here the second knife-holder 4 has a slidebar, 10, similar to that shown at 10 but parallel therewith and working in slots, 11, of

the different knife-holders 4, while the third knife-holder has a slide-bar, 10*, which works in slots or guide-grooves, 11", in the knife-holders. It will be evident from Fig. 2 that inany adjusted position of any knifeholder its extended support will be effective to prevent tipping movement crosswise of the knife'no matter how close together the knife-holders may be.

Referring to'Figs. 3 and 4 a. modification of the invention is illustrated in which all of the parts are similar tothose just described and are indicated by corresponding reference characters, except that the exthat though their T-heads overlap horizontally interference with one another is avoided by placing them one above another, as clearly shown in Fig. '3, the'forward edge of each being inclined at the same angle as the inclined guide-surface 2 of the cutterbar 2. It will be evident that when the gib 8 is tightened after the knife-holders 4 with their T-shaped extended supports 13, etc, have been adjusted lengthwise of the cutter bar 2, all of said extended supports will be firmly held to the coacting way of the cutterb-ar and will prevent tipping movement of the knives and knife-holders 4, substantially as in the constructionshown' in Figs. 1 and 2.

Figs. 5 and 6 illustrate a modification of the invention in which is shown the applica: tion of the same principle to the lower knife holders and the'knives or dies thereof, corresponding parts being indicated by the same reference characters as in theprevious views. The lower knife-holders indicated by 5Qare shown here as having bearings, 14,

14E and 14", extending transversely therefrom near the rear side of the machine, these bearings being disposed in pairs at opposite sides of the knife-holders 5 with their openings in alinement with each other. Each pair of bearings is in a different position from every other order to avoid interference, these bearings being illustrated as extending from brackets, 16, 16 and 16, depending from the knife-holders -5 in different positions. Through the bearings 14:, let and 14 pass guide-rods, such as 17, 17 and 17, parallel. with one another and securely fastened to thebase or bed portion of the machine. It'will be evident from Figs. 5 and 6 that in the case of the lower knives also, extended crosswise supports are provided which prevent tipping or canting of the lower knives and their dies 7; that all of the lower knife-holders may also be adjusted so as to be in contact with one another to cut the slots close together in the material, and that the extended supports for the different knife-holders are so arranged or staggered, substantially as in the case of the upper knife-holders and cutters, that there is no interference of any of these extended supports with any other knife-holder or knife.

It will be understood that both the upper and lower knife-holders may be adjusted as usual and simultaneously to corresponding positions lengthwise of the cutter-bar 2 and the bed 3, and then firmly secured in place in the new relation, and that no matter what the positions may be to which the various complementary upper and lower knife-holders and knives are moved, each will. always have a relatively long extended support for preventing any tipping or canting of either the upper or the lower knives crosswise of their cutting paths.
